The developer of Purple Martians, another one that I reviewed a while back had responded on Itch - since he didn't replied to my Post it took me quite long to notice.

After noticing I had some mail exchange with him. Development of the game is still highly active; a more up-to-date version than the one on Itch can be DLed at https://github.com/mweiss001/purple_martians
